SPECIFICATION; forming part of Letters Patent No. 289,222, dated November 27, 1883.

Application filed F'orember 10.1882. (No model.)

ToaZZ whom it may concern.-

Be it known that I, RoswnLL M. CLARK, a citizen of the United States, residing at Mo- Pherson, in the county of McPherson and State of Kansas, have invented a new and usefulImprovem ent inGorn-Planters, of which the following is a specification.

Figure lis a perspective view of this devlce. 3 is a View, partly in side elevation and partly in section, to show parts of the mechanism operating the plunger, and the plunger in its relation to the wheel. side elevation to show means for stopping the revolution of the wheels. Fig. 5 is a detail of theperforated felly through which the plunger plays.

This invention belongs to that class of devices generally known as corn-planters; and the novelty in. the present instance consists in the general details of the construction and combination of allthe parts, whereby is produced a simple, easily-operated, and very durable deq i vice, as will now be more fully set out and explained.

In the accompanying drawings, A denotes any suitable frame properly mounted on the axle B, on the ends of which axle are placed the wheels 0 G. On this frame is placed, in any convenient way, a seat, D, for the-- driver. The shaft attachment is made at a, or in any of the well-known ways. The

: plunger F is attached... The hopper Ehas the usual revolving charger, E, in its lower or discharge end. The charger E is rotated by i r means of the pin 0 on the hub of the wheel 0, r, r 40 acting on one of the projections c of the wheel or flange e, which carries the revolving charger E, and thus allows the corn to drop into the hopper-spout e. The several parts are so constructed and arranged that just before the seed has been dropped the cam G, placed on the axle B, inside of the enlarged hub. c? of the wheel G, has been operated on by the roller S, journaled in the upper end of the arm f of the plunger F, and thrust it outward, and this movement carries forward the IOdi, to which the jaws I are hinged, so as to cause said j aws to project through the opening 0 in the tire Fig. 2 is a top plan View of same. Fig.

Fig. 4 is a detail in or felly of the wheel. When said opening has come within about seven-eighths of an inch (more or less) of the ground, in the revolution of the wheel, the sharp end or edge formed by the thrust-out and closed jaws will be readily driven by the weight of the wheel and its momentum into the ground. The corn flowing down the hopper-spout 6 has, just before the jaws have reached the ground, been carried inside the closed jaws of the plunger by means of the funnel-shaped conveyerf the top of which has come at the proper moment under the end of the spout a. When the jaws are nearly in a vertical position in the ground, the roller S sliding or moving off the longer part of cam G, the spring f 2 on the plunger-shaft causes the jaws to be retracted up through the slot 0 of the wheel tire or felly, and this movement opens the jaws and allows the corn to fall into the furrow or hole they have just made, while the continued revolution of the wheel serves to sufficiently cover the corn with earth. In the continued revolution of the wheel the ends of the jaws are thus brought flush with the outer surface of the again has made about seven-cighths of arevolution, when they are again thrust out, asabove described. It may be found best to have a plate, K, extend inside the felly as a guide or shield for the plunger to move on. On the outer edge of the felly or tire of the wheel is the marker L, which impresses the ground, to show where the seed has been deposited.

While I have shown one plunger on the wheel, there may be more, if desired, the changes in construction for this purpose being merely mechanical; also, there may be two or more wheels 0 on the axle, which is prolonged for the purpose, each fitted with plungers and the other operative parts, as above described. As corn is usually planted about fortyfour inches apart, the plungers are placed on the wheels of this planter at such suitable distances apart as to insure that the corn shall be dropped at the desired distance.

apart, so that by starting a line at each end of the field the corn would be dropped in checkrows each way, only varying where the uneven ground may cause the wheels to lose the distance. To guard against this is the especial object of the projection or marker L on the tireor felly of the wheel. When any such irregularity occurs, the driver, by means of lever N, can turn the wheels 0 C, &c., forward or backward, and thus cause the plungers to operate as desired. The scraper M will keep the tire of the wheel clear of dirt. The cam G will be steadied by the rod h, which extends across to the opposite side of frame A.

WVhen it is desired to stop the operations of the plunger and seed-hopper, the cam G can be moved on the axle B by means of lever H and rod h,'so that. it will not impinge on the roller S. This movement of the lever H will also act on the frame and withdraw the flange 6 so that it cannot be operated by pin 0.

This device'is not complicated in structure, nor costly, and inoperation furnishes a most excellent and perfect planter.

Having thus described my invention, what I consider new, and desire to secure by Letters Patent, is

1. In. a corn-planter, the combination of the seed-hopper E, mounted on the frame A, and having the spent 6 and revolving charger E, the lever H, hub 0 pin 0, and the cam G, substantially in the manner and for the purposes set forth.

2. In a corn-planter, the plunger F, having arm f, spring f conveyerf, arm 13, and jaws I, combined with the wheel 0, having hub c and a cam, G, and provided with an opening, 0*, in its tire, substantially as described.

3. In a corn-planter, a seed disk and hopper, adapted to be adjusted as described, combined with a seed-plunger actuated automatically, and with the lever N, the stop ,0, and flange 12, substantially as and for the purposes described.

4. In combination with the wheel 0, having opening 0 in its tire, the plunger F,- having hinged jaws I, and the guide or shield K, sub stantially as and for the purposes set forth.

5. The sliding cam G, combined with the axle of wheel 0, and with the plunger F and jaws I, substantially in the manner and for the purposes described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
